Problems solved by technology

The height of the hood should not be lowered due to the requirements of shape, wind resistance and lower visibility, and there is a fixed ground clearance requirement for the layout of the engine compartment, which has caused several major contradictions between the layout and the regulations. It is far enough to meet the requirements only by partially weakening the design. no request

Abstract

The invention belongs to the technical field of automobile accessories, and discloses a five-connecting rod hinge structure of an active pedestrian protection engine cover. The structure comprises a base seat, a first bracket, a second bracket, a hinge body, an engine cover connecting rod and a locking piece, wherein one end of the first bracket is hinged on the base seat, and the other end of thefirst bracket is hinged on the hinge body; one end of that second bracket is hinged on the base seat, and the other end of the second bracket is hinged on the hinge body; the first bracket, the second bracket and the hinge body form a four-rod mechanism; a first locking hole is formed in the hinge body; and the engine cover connecting rod is hinged on the hinge body, and the locking piece locks the engine cover connecting rod in the first locking hole. The five-connecting rod hinge structure of the active pedestrian protection engine cover has the advantages of stable structure and high safety.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a five-link hinge structure for an active pedestrian protection engine cover. Background technique [0002] With the imminent enforcement of pedestrian protection regulations and the addition of pedestrian protection as an evaluation standard in 2018 CNCAP, pedestrian protection technology has become more and more common. At present, pedestrian protection design for local areas or points is mainly through the application of energy-absorbing materials on the body, and the partial hood Weakening, highlighting feature lines, crushing bracket design, etc. The height of the hood should not be lowered due to the requirements of shape, wind resistance and lower visibility, and there is a fixed ground clearance requirement for the layout of the engine compartment, which has caused several major contradictions between the layout and the regulations. It is far enough to meet the require...
